OBJECTIVE To evaluate the clinical benefit of pre-procedural antiplatelet therapy in patients undergoing transfemoral (TF) transcatheter aortic valve implantation (TAVI). METHODS OCEAN (Optimized transCathEter vAlvular interveNtion)-TAVI is a prospective, multicentre, observational cohort registry, enrolling 749 patients who underwent TAVI from October(More)
OBJECTIVES This study describes the characteristics of a real-world Asian patient population treated with transcatheter aortic valve replacement (TAVR) and evaluates their clinical outcomes. BACKGROUND No previously reported randomized or observational studies adequately assess the safety and efficacy of TAVR in an Asian population. METHODS The Asian(More)
To evaluate the 2-year results obtained with self-expandable stent for chronic total occlusion (CTO) of the iliac artery, a retrospective study was performed of patients who underwent endovascular therapy (EVT) for chronic iliac artery CTO who presented from April 2007 to September 2012. 82 patients with 86 occluded iliac arteries underwent successful(More)
BACKGROUND Gait speed reflects an important factor of frailty and is associated with an increased risk of late mortality in patients with cardiac disease. This study sought to assess the prognostic value of gait speed in elderly patients who underwent transcatheter aortic valve replacement. METHODS AND RESULTS We investigated the 5-m or 15-feet gait speed(More)
OBJECTIVES This study investigated the safety and prognosis of ultra-long second DES (UL-2nd DES) implantation in real-world practice. BACKGROUND Long stenting is a widely known predictor of stent thrombosis (ST) or target lesion revascularization (TLR) in first-generation drug-eluting stents (DES). METHODS Participants were 1,669 patients (2,763(More)
BACKGROUND This retrospective study assesses the safety and efficacy of using a thrombus injection for treatment a peripheral artery perforation. METHODS AND RESULTS From March 2013 to April 2016, we performed 1,152 endovascular treatment (EVT) at our hospital. Of these, 28 peripheral artery perforations occurred during the EVT procedure and 20 were(More)
PURPOSE To evaluate the clinical efficacy of poststenting fractional flow reserve (FFR) in terms of predicting restenosis in superficial femoral artery (SFA) disease. METHODS This prospective, single-center, nonrandomized study enrolled 48 patients (mean age 76±9 years; 38 men) with 51 SFA lesions from July 2013 to June 2014. Mean FFR (distal mean(More)
The relationship between cardiac rhythm and adverse events after transcatheter aortic valve implantation (TAVI) remains unclear. To compare the prognostic impact of preexisting atrial fibrillation (AF) and new-onset AF (NOAF) after TAVI, we assessed 1,124 patients (846 with sinus rhythm [SR], 49 with NOAF, and 229 with preexisting AF) who underwent TAVI(More)
OBJECTIVE The Wound, Ischemia, foot Infection (WIfI) classification system is used to predict the amputation risk in patients with critical limb ischemia (CLI). The validity of the WIfI classification system for hemodialysis (HD) patients with CLI is still unknown. This single-center study evaluated the prognostic value of WIfI stages in HD patients with(More)
OBJECTIVES The aim of this study was to determine the impact of pre-existing right bundle branch block (RBBB) on clinical outcomes after transcatheter aortic valve replacement (TAVR). BACKGROUND The impact of pre-existing RBBB on clinical outcomes after TAVR is unknown. METHODS Between October 2013 and August 2015, 749 patients undergoing TAVR using the(More)
